Are 23" mounting rails available for NetShelter SX cabinets?

Cause:
A customer has 23 inch wide EIA equipment and wants to mount it into a NetShelter SX cabinet.

Resolution:

All 42U and 48U NetShelter SX 750 mm (30") wide cabinets are available with 23" mounting rails installed. These cabinets are not in stock, but they can be built to order. Please contact your reseller or distributor for pricing and availability.
For customers who already own a 42U 750mm wide SX cabinet with 19" mounting rails we offer AR7510. This is a set of four replacement 23" EIA mounting rails, 42U.
We do not currently offer 48U 23" EIA mounting rails as a stand alone sku, only pre-installed into the cabinet as described above.
We do not currently offer 45U 23" EIA mounting rails. If you have an opportunity please check with your Schneider Electric representative to see if they can be provided as a Custom.
23" wide EIA mounting rails do not install into 600 mm (24") wide cabinets because the cabinets are not wide enough.
